About this 5.03ct natural oval diamond

This 5.03ct natural oval sits in the over five carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2151528674. Listed at 16 retailers as of October 29, 2026, with prices from $142,855 to $249,038, a $106,182 spread on the same certified stone. MOH London lists it at $249,038. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
